Example, the utility model is further elaborated.
Fig. 1 to Fig. 7 is referred to, the numerical control gong machine that the utility model embodiment is provided is used for will be multiple on big plate 100
The cutting of circuit board 200 is got off, and its cutting process is mainly included the following steps that：
S1：Numerical control gong machine 20 is provided, the big plate 100 is fixed on to the workbench 21 of the numerical control gong machine 20, it is described
Numerical control gong machine 20 includes being fixed with the workbench 21 of the big plate 100, control system, controls it to move by the control system
Backboard 22, be fixed on the backboard 22 and driven simultaneously for the main shaft 23 of big plate 100 described in cutting, by the main shaft 23
And for the gong knife 24 of big plate 100 described in cutting and for compressing the circuit board 200 so that the circuit board 200 is kept
Fixed foot device 25, the foot device 25 includes the first cylinder 251 and described first for being fixed on the backboard 22
Cylinder 251 connects and drives the closure 252 moved up and down, under the closure 252 by first cylinder 251
Side and be fastened on the closure 252 with the closure 252 formation accommodation space 254 presser feet cup 253, one end it is solid
Due to the closure 252 and the other end connect the presser feet cup 253 with the second cylinder 255 of presser feet cup 253 described in support with
And presser feet 253 bottoms of cup and the presser feet pad 257 for compressing the circuit board 200 are fixed on, second cylinder 255 is wrapped
Include the second cylinder body 2551 for being fixed on the closure 252 and the second flexible cylinder is driven by second cylinder body 2551
Axle 2552, the presser feet cup 253 is more than the diameter of the second cylinder axis 2552 provided with diameter and supplies second cylinder axis
2552 prop holes 2531 passed through, the one end of second cylinder axis 2552 away from second cylinder body 2551 is described provided with being held in
Supporting plate 256 of the presser feet cup 253 so that presser feet cup 253 to be held up；It is emphasized that big plate 100 can pass through a variety of sides
Formula is fixed with workbench 21, for example, in the periphery pin hole of big plate 100, being then fixed in workbench 21 by pin
On, or the setting gas folder on workbench 21, big plate 100 and workbench 21 are carried by fixation by gas folder.
S2：Start the numerical control gong machine 20 and control the backboard 22 to drive under the main shaft 23 and the foot device 25
Move so that the presser feet pad 257 is held in the circuit board 200, control the main shaft 23 to move, utilize the edge of gong knife 24
The edge of circuit board 200 carries out first time cutting, and multiple connections circuit board 200 and the company are reserved during first time cutting
Connect framework 102 interrupts position 101；It is to be appreciated that in this step, due to the cutting of circuit board 200 during pass through all the time
Multiple positions 101 of interrupting are fixed with connection framework 102, therefore, on the premise of big plate 100 is fixed, and circuit board 200 is for the first time
Displacement will not be produced during cutting, so as to ensure that the machining accuracy in first time cutting；It is emphasized that in the step
Presser feet pad 257 is held in circuit board 200 in rapid, but does not compress circuit board 200, and presser feet pad 257 still can be with opposing circuit
Plate 200 is slided, it is thereby achieved that the cutting to big plate 100.
S3：Control second cylinder axis 2552 to extend and separate the supporting plate 256 and the presser feet cup 253 so that
The presser feet cup 253 is pressed in the circuit board 200；It should be understood that in this step, the second cylinder axis 2552, which extend, to be caused
The presser feet pad 257 that presser feet cup 253 loses below the power to pop-up, presser feet cup 253 can be pressed circuit board 200 due to the effect of gravity
Tightly on workbench 21, so that circuit board 200 is fixed；
S4：Second of cutting, controls the main shaft 23 to move, and described interrupts the gong of position 101 by each using the gong knife 24
Break to realize that the circuit board 200 and the connection framework 102 are separated.Then second of cutting is carried out, the gong of position 101 will be interrupted
Disconnected, during gong breaks and interrupts position 101, because presser feet pad 257 compresses circuit board 200, circuit board 200 will not still be sent out
Raw displacement, thus it is guaranteed that the machining accuracy of second of cutting, after cutting twice, realizes circuit board 200 with being connected frame
The separation of frame 102.It should be noted that during second of cutting, after presser feet cup 253 compresses circuit board 200, presser feet
253 opposing circuit boards 200 of cup are static, because the diameter of prop hole 2531 is more than the diameter of the second cylinder axis 2552, therefore, main shaft 23
It relative presser feet cup 253 can be moved in the horizontal direction with closure 252, therefore second of cutting to big plate 100 can be realized.
The utility model embodiment is avoided during the cutting of circuit board 200 using alignment pin fixing circuit board 200,
So as to simplify procedure, it is ensured that machining accuracy.
Fig. 3 to Fig. 7 is referred to, further, the closure 252 is provided with the tracheae blown inwards for external device (ED)
2521 and opening towards presser feet cup 253 and the air drain 2522 communicated with the tracheae 2521；
Step S3 also includes blowing to increase 257 pairs of the presser feet pad circuit board 200 into the tracheae 2521
Pressure and one layer of air film 300 is formed between the closure 252 and presser feet cup 253 to reduce the closure 252
With the frictional force between presser feet cup 253.The utility model embodiment sets tracheae 2521 on closure 252, and utilizes
External equipment is blown into tracheae 2521 so that closure 252 is separated with presser feet cup 253 and in closure 252 and presser feet cup
